Chopped/Heartwarming

Watch the relationship between the two finalists build over this episode and try not to tear up.
The finale of Chopped Champions, in which the winner's little daughter is on set (unbeknownst to him). I dare you not to cry (starting at about 5:27 in the linked video). Even Alex Guarnaschelli cried!
The finale of the Chopped All-Stars tournament. After the winner is congratulated, his son is on set and he shows the judges why he did the tournament: to support the charity that helped his son out. The congrats starts about 12:34 in the linked video, the son appears at 13:21.
At the end of the eighth-season Second Chance episode, Lance Nitahara won the final round, but gave some of the prize money to his competitor so she could fly home to France to see her ailing grandmother. It was pretty clear nobody was expecting it.
Pretty much the entire episode where four school lunchladies competed.
The entirety of the Judges' episode of the 2nd All-Stars Tournament. Geoffrey Zakarian, Amanda Freitag, and Aaron Sanchez watching four of their fellow judges compete, and hating every single elimination, each judge hugging and congratulating the eliminated competitor.
- Chris Santos' elimination might have been the most tearjerking/heartwarming. He talks about his charity, a foundation treating patients of a disease which only strikes girls (his young cousin being one such patient), bringing tears to Alex Guarnaschelli's eyes again and causing Amanda Freitag to practically vault the table to hug him.
